64x16 Big LED Matrix Clock / Temperature

Sure Electronics 0832 displays X 4 connected together to make a large led matrix display. I built the interface on veroboard using a PIC16F913 @ 20MHz, DS1307 Real Time Clock & LM35 Temp sensor to gather the time and temperature and send the infomation to the display modules. This also has a LDR to adjust PWM of the display acording to the amount of light in the room.
